Epipleoneura albuquerquei Machado 1964: 9 –15, figs. 4–5 (new species, description of male, illustration of S 10 in lateral and dorsal view, type material at ABMC). Lencioni 2005: 173, figs. 103 a–b (references, type locality, distribution, described stages, reproduction of original illustrations of male S 10 in lateral and dorsal view). Garrison et al. 2010 : 352, 354, fig. 2340 (included in list of species, illustration of epiproct in posterior view). Pessacq et al. 2012 : 4 (included in list of Brazilian Protoneuridae).

Specimens examined. Holotype ♂, Brazil, Pará State, Parque Nacional do Tumueumaque, Óbidos, Aldeia Turió (Óbidos: 1°54’05”S, 55°31’16”W), leg. A.B.M. Machado & Acewa, ii 1963, ABMM.

Diagnosis. The cercus and epiproct (Figs 25 a–c) morphology in E. albuquerquei is unique and distinguishes it from all other males of the genus; the cercus dorsal branch is parallel to main body axis and rounded in cross section, the ventral branch is small, approximately rounded and has two small tubercles on its medial side, difficult to see (Fig. 25 b, c), which are unique for this species. This species shares with E. angeloi Pessacq & Costa, 2010, and E. williamsoni Santos, 1957, a small black spine close to cercus apex on its inner margin (Fig. 25 a, b), but it is more developed in E. albuquerquei, almost like a posteriorly directed apical hook. The epiproct is also characteristic; its branches (Fig. 25 d) are parallel, narrow and long and separated at their bases by a considerable distance. Segment 3 of genital ligula (Fig. 52) is approximately quadrangular in ectal view, its sides are slightly elevated and the apex has a very shallow cleft; the postero-lateral projection is triangular without a developed peduncle. Female unknown.

Distribution. Northern Brazil, in the States of Pará (type locality: Munhene river) and Amazonas (W of Itacoatiara, Garrison et al. 2010).

Notes. The type locality given by Machado (1964) “Munhene river, tributary of river Parú do Oeste, 10 km from Aldeia dos Índios Tiriyó-Aramágoto, Óbidos (05°48’23” S, 63°32’13” W)” differs with the information on the holotype label (provided on specimen examined as mentioned above under specimens examined), I contacted Prof. Machado, who confirmed that the correct type locality is the one given in his paper (Machado 1964). The cerci of the holotype are separated from S10.
